Human activity has increased the extent to which solar energy is reflected back from the Earth, thus modifying the global radiation balance. This has been achieved by the destruction of forests and desertification. The planetary albedo is also altered by the introduction of aerosols and particles into the atmosphere.
It has been estimated that the reflection of solar radiation may have increased by 1 W per square metre over the whole of human history, and probably by 0.2 W per square metre over the last 30 years. It is estimated that over the next 100 years this may be increased by from 0.3 to 1 W per square metre. The expected proliferation of solar collectors would contribute to this effect.
The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.
The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
